Cause

Det ser ut som att unicast-registrering är problemet. Unicastagent-listan saknades på två noder

Resolution

Lägg till de saknade unicast-agentposterna
 
esxcli vsan cluster unicastagent add -t node -u -U < unicastSupport> -a -p -i

Then 

Exempel:
  
 esxcli vsan cluster unicastagent add -t node -u 57ea62b0-9df6-6532-110c-9457a55a37d0 -U true -a XX.XXX.XXX.XX-p 12321 -i vmk3
